CLUTCH PACK CLEANING AND
INSPECTION
1. Separate the pack in to the following components:
a. Seven fiber plates.
b. Seven steel plates.
c. One narrow fiber plate.
d. One damper spring.
e. One damper spring seat.
Compressed air can pierce the skin and flying debris from
compressed air could cause serious eye injury. Wear
safety glasses when working with compressed air. Never
use your hand to check for air leaks or to determine air
flow rates. (00061a)
2. Wash all parts, except fiber (friction) plates and bearing
in the clutch hub/shell, in cleaning solvent. Blow dry with
compressed air.
3. Examine the clutch components as follows:
a. Check all clutch plates for wear and discoloration.
b. Inspect each steel (drive) plate for grooves.
c. Place each steel plate on a flat surface. Using a feeler
gauge, check for flatness in several places. Replace
any plates that are damaged or are warped more than
0.006 in. (0.15 mm).
4. Inspect the damper spring for cracks or distortion. Install
a new spring if either condition exists.
5. See Figure 5-15. Check fiber plates for thickness.
a. Wipe the lubricant from the eight fiber plates (7 regular
and 1 narrow) and stack them on top of each other.
b. Measure the thickness of the eight stacked fiber plates
with a dial caliper or micrometer. The minimum
thickness must be 0.661 in. (16.789 mm).
c. If the thickness is less than specified, discard the fiber
plates and steel plates. Install a new set of both fric-
tion and steel plates.
6. See Figure 5-16. Inspect primary chain sprocket (1) and
the starter ring gear (2) on the clutch shell. If either
sprocket or ring gear are badly worn or damaged, replace
the clutch shell. See 5.6 PRIMARY
7. Inspect slots that mate with the clutch plates on both clutch
shell (4) and hub (3). If slots are worn or damaged, replace
shell and/or hub. See 5.6 PRIMARY
